To all whom it may concern lde it known that l, WILLIAM E. FFINE, a citizen of the United @tates of America, residing at 'lloledo, in the county of Lucas and i itate of Uhio, have invented certain new and useful llmprovements in Gar-Doorltiocking Devices, of which the following is a specification. My invention relates to new and useful improvements in car door locking devices and especially to a locking device that ia designed to hold and lock the drop bottil tom doors of a freight car.

Une of the principal objects of the present invention is to provide a small casting in the form of a housing in which there is located a pivotal arm, a latch member pivoted to said arm and a dog for retaining the pivotal arm and the latch member in their locked position; the casting to be secured to the bottom of the drop bottom door and at one corner thereof, so that the latch member will engage and be supported on a hook which is fastened to the side of the car.

btill another object'fof the invention is to provide a'locking device which will be very compact, relatively' strong and readily applied to the drop doors of freight cars.

Still another object is to provide a double faced hook as, in a number of the cars in use today, drop bottom doors are so arranged that the outer ends of the doors when closed will be adjacent, therefore, a double faced, hook placed on the side of the car oentrally of the inner ends of the door will serve as a supporting means for the two doors, provided, of course, an engaging member for the hook is placed on each of said doors.

lln the present embodiment, l have partially shown the adjacent edges of two doors, two locking devices, one being fastened to each door, and a common central plate, and

it is to be understood that a similar arrangement will be used on the other side of the car, as the doors are supported at both of their sides.

Of course, if the drop doors are singularly arranged in the car, a single faced plate may be used in each instance rather than a double one as, shown in the present embodiment.

With theabove objects in view, the in vention consists in certain new and novel arrangements and combination of parts as will be hereinafter more fully described and pointed out in the drawings.

in the drawings showing a preferred form of the invention- Fig. l is a view in elevation showing a fragmentary side portion of a car, a part of two doors, two locks, secured to the inner adjacent edges of the door, oneof said locks being partly in section for the sake of clearness.

Fig. 2 is a sectional view taken along line 2-2 of Fig. 1.

Fig. 3 is a sectional view takenalong line 3-3 ofFig. 1, looking in the direction of the arrow.

Fig. d is a vertical view taken on line M of Fi 1.

in the rawings, a fragmentary portion 1 of the side of a-car is shown as well as a' portion of'two doors 2 and 3, which doors swing upwardly towards each other as clearly shown in Fig. 1.

Both of these doors are provided with transversely extending angle irons at, each having a leg riveted to the door bottom, these angles extendin slightly beyond the sides of the door as swam in Figs. 2 to 4t inclusive.

@ther transversely extending members might be used rather than angle irons, but l have found in practice that they are preferable due to their lightness, mode of attachment and strength.

Referring now in particular to the gist of the invention, there is shown in the several views a form of housing 5 which is plfif'l erably cast, this housing comprising a top securing plate 6, as shown in the dotted lines in Fig. 2, a small web plate 7 and the main body plate 8' having the depressed portion 9 formed therein, from which extends the short bearings 10 and 11 which are drilled to receive rivets.

The forward end of this housing is provided with a top wall 12, a bottom wall 13, a front wall it and an outer wall'15 forming a box like chamber. The front wall it having formed therein a slot 16, the edges of which are slightly rounded as at 17 to bottom wall 13 and extending from the outer wall l5to the body plate 8 is a flange 18 which is also slightly rounded to form a resting point for the latch member 20 now to bedescribed. Pivotally mounted on the bearing 10 is the short arm 19 to the outer end of which is pivoted the latch 20 which is bifurcated as at 21 while at its outer end a portion is cut outcentrally to form the stubs or nibs 22. This latch member 20 passes throughthe slot 16 in the front wall 14 of the housing 5 as heretofore mentioned and is adapted to engage and'be supported on a ledge 23 formed on the edge of a plate 24:, the two outer stubs 22passing beyond the edge of the plate directly above the ledge 23, as may be clearly seen in Fig. 2.

Pivotally secured to the other bearin 11 is an irregular shaped cam or dog 25 w ich is provided with a lug 26 for manipulating the same, and extending between the two bearings 10 and 11 is the short plate or strap 27 which holds the arm 19 and the 25 on the housing.

do %he housing 5 in practice is secured to the door by riveting through the plate 6 and through the top wall 12, an offset end portion of the plate 8 allowing the top wall 12 to lie snugly against the angle iron 4. v The locking plate 24 has its opposite edge similarly arranged, that is,:with a ledge so that the one plate will suffice for the supporting of the two doors at one side of the car, while a similar arrangement will be provided on the opposite sides of the door and car.

The operation of the lock isexceedingly simple and will be readily understood from the foregoing description. When the door is raised to its closed position, the latch member will rest on the ledge 23 of the plate 24 and the dog will be forced downwardly against the arm 19, thus holding the armand latch member in their locked position. To release the door, the dog will be swung back I and the latch member retracted by forcing its inner pivotal end upwardly as shown in the dotted lines in Fig. 1 so that the latch no longer rests on the ledge of the hook.

From the foregoing it will be seen that I have provided a means for supporting and lockin the drop doors of a car that is-relatively inexpensive to manufacture and made upof but a 'few parts, which are conveniently housed and in a relatively small space.

Many slight changes may be made without in any way departing from the spirit and scope of the invention.
